# forked-daapd
forked-daapd is a Linux/FreeBSD DAAP (iTunes), MPD (Music Player Daemon) and
RSP (Roku) media server.
It has support for AirPlay devices/speakers, Apple Remote (and compatibles),
MPD clients, Chromecast, network streaming, internet radio, Spotify and LastFM.
It does not support streaming video by AirPlay nor Chromecast.
DAAP stands for Digital Audio Access Protocol, and is the protocol used
by iTunes and friends to share/stream media libraries over the network.
forked-daapd is a complete rewrite of mt-daapd (Firefly Media Server).

## Getting started
After installation (see [INSTALL](https://github.com/ejurgensen/forked-daapd/blob/master/INSTALL))
do the following:
1. Edit the configuration file (usually `/etc/forked-daapd.conf`) to suit your
needs
2. Start or restart the server (usually `/etc/init.d/forked-daapd restart`)
3. Wait for the library scan to complete. You can follow the progress with
`tail -f /var/log/forked-daapd.log`
4. If you are going to use a remote app, pair it following the procedure
[described below](#using-remote)
## Supported clients
forked-daapd supports these kinds of clients:
- DAAP clients, like iTunes or Rhythmbox
- Remote clients, like Apple Remote or compatibles for Android/Windows Phone
- AirPlay devices, like AirPort Express, Shairport and various AirPlay speakers
- Chromecast devices
- MPD clients, like mpc (see [mpd-clients](#mpd-clients))
- MP3 network stream clients, like VLC and almost any other music player
- RSP clients, like Roku Soundbridge
Like iTunes, you can control forked-daapd with Remote and stream your music
to AirPlay devices.
A single forked-daapd instance can handle several clients concurrently,
regardless of the protocol.
Here is a list of working and non-working DAAP and Remote clients. The list is
probably obsolete when you read it :-)

## Using Remote
If you plan to use Remote for iPod/iPhone/iPad with forked-daapd, read the
following sections. The pairing process described is similar for other
controllers/remotes (e.g. Retune), but some do not require pairing.
### Pairing with Remote on iPod/iPhone
If you just started forked-daapd for the first time, then wait til the library
scan completes before pairing with Remote (see [library](#library)). Otherwise
you risk timeouts. Then do the following.
The Quick Way:
1. Download and run the helper script from [here](https://raw.githubusercontent.com/ejurgensen/forked-daapd/master/scripts/pairinghelper.sh)
Or, if that doesn't work:
1. Start forked-daapd
2. Start Remote, go to Settings, Add Library
3. Look in the log file for a message saying:
```
"Discovered remote 'Foobar' (id 71624..."
```
This tells you the name of your device (Foobar in this example).
If you cannot find this message, it means that forked-daapd did not receive
a mDNS announcement from your Remote. You have a network issue and mDNS
doesn't work properly on your network.
4. Prepare a text file with a filename ending with .remote; the filename
doesn't matter, only the .remote ending does. This file must contain
two lines: the first line is the name of your iPod/iPhone/iPad, the second
is the 4-digit pairing code displayed by Remote.
If your iPod/iPhone/iPad is named "Foobar" and Remote gives you the pairing
code 5387, the file content must be:
```
Foobar
5387
```
5. Move this file somewhere in your library
At this point, you should be done with the pairing process and Remote should
display the name of your forked-daapd library. You should delete the .remote
file once the pairing process is done.
If Remote doesn't display the name of your forked-daapd library at this point,
the pairing process failed. Here are some common reasons:
#### Your library is a network mount
forked-daapd does not get notified about new files on network mounts, so the
.remote file was not detected. You will see no log file messages about the file.
Solution: Set two library paths in the config, and add the .remote file to the
local path. See [Libraries on network mounts](#libraries-on-network-mounts).
#### You did not enter the correct name or pairing code
You will see an error in the log about pairing failure with a HTTP response code
that is *not* 0.
Solution: Copy-paste the name to be sure to get specials characters right. You
can also try the pairinghelper script located in the scripts-folder of the
source.
#### No response from Remote, possibly a network issue
If you see an error in the log with either:
- a HTTP response code that is 0
- "Empty pairing request callback"
it means that forked-daapd could not establish a connection to Remote. This
might be a network issue.
Solution: Sometimes it resolves the issue if you force Remote to quit, restart
it and do the pairing proces again. Another trick is to establish some other
connection (eg SSH) from the iPod/iPhone/iPad to the host.
Otherwise try using avahi-browse for troubleshooting:
- in a terminal, run `avahi-browse -r -k _touch-remote._tcp`
- start Remote, goto Settings, Add Library
- after a couple seconds at most, you should get something similar to this:
```
+ ath0 IPv4 59eff13ea2f98dbbef6c162f9df71b784a3ef9a3 _touch-remote._tcp local
= ath0 IPv4 59eff13ea2f98dbbef6c162f9df71b784a3ef9a3 _touch-remote._tcp local
hostname = [Foobar.local]
address = [192.168.1.1]
port = [49160]
txt = ["DvTy=iPod touch" "RemN=Remote" "txtvers=1" "RemV=10000" "Pair=FAEA410630AEC05E" "DvNm=Foobar"]
```
Hit Ctrl-C to terminate avahi-browse.
The name of your iPod/iPhone/iPad is the value of the DvNm field above. In this
example, the correct value is Foobar. To check for network issues you can try to
connect to address and port with telnet.
### Selecting output devices
Remote gets a list of output devices from the server; this list includes any
and all devices on the network we know of that advertise AirPlay: AirPort
Express, Apple TV, ... It also includes the local audio output, that is, the
sound card on the server (even if there is no soundcard).
If no output is selected when playback starts, forked-daapd will try to
autoselect a device.
forked-daapd remembers your selection and the individual volume for each
output device; selected devices will be automatically re-selected, except if
they return online during playback.
## AirPlay devices/speakers
forked-daapd will discover the AirPlay devices available on your network. For
devices that are password-protected, the device's AirPlay name and password
must be given in the configuration file. See the sample configuration file
for the syntax.
## Chromecast
forked-daapd will discover Chromecast devices available on your network. There
is no configuration to be done. This feature relies on streaming the audio in
mp3 to your Chromecast device, which means that mp3 encoding must be supported
by your ffmpeg/libav. See [MP3 network streaming](#mp3-network-streaming-streaming-to-ios).
It is also required that forked-daapd is built with "--enable-chromecast".
## Local audio through ALSA
In the config file, you can select ALSA for local audio. This is the default.
When using ALSA, the server will try to syncronize playback with AirPlay. You
can adjust the syncronization in the config file.
## Local audio, Bluetooth and more through Pulseaudio
In the config file, you can select Pulseaudio for local audio. In addition to
local audio, Pulseaudio also supports an array of other targets, e.g. Bluetooth
or DLNA. However, Pulseaudio does require some setup, so here is a separate page
with some help on that: [README_PULSE.md](https://github.com/ejurgensen/forked-daapd/blob/master/README_PULSE.md)
Note that if you select Pulseaudio the "card" setting in the config file has
no effect. Instead all soundcards detected by Pulseaudio will be listed as
speakers by forked-daapd.
You can adjust the latency of Pulseaudio playback in the config file.
## MP3 network streaming (streaming to iOS)
You can listen to audio being played by forked-daapd by opening this network
stream address in pretty much any music player:
http://[your hostname/ip address]:3689/stream.mp3
This is currently the only way of listening to your audio on iOS devices, since
Apple does not allow AirPlay receiver apps, and because Apple Home Sharing
cannot be supported by forked-daapd. So what you can do instead is install a
music player app like VLC, connect to the stream and control playback with
Remote. You can also use MPoD in "On the go"-mode, where control and playback is
integrated in one app (see (#mpd-clients)).
Note that MP3 encoding must be supported by ffmpeg/libav for this to work. If
it is not available you will see a message in the log file. In Debian/Ubuntu you
get MP3 encoding support by installing the package "libavcodec-extra".
## Supported formats
forked-daapd should support pretty much all media formats. It relies on libav
(or ffmpeg) to extract metadata and decode the files on the fly when the client
doesn't support the format.
Formats are attributed a code, so any new format will need to be explicitely
added. Currently supported:
- MPEG4: mp4a, mp4v
- AAC: alac
- MP3 (and friends): mpeg
- FLAC: flac
- OGG VORBIS: ogg
- Musepack: mpc
- WMA: wma (WMA Pro), wmal (WMA Lossless), wmav (WMA video)
- AIFF: aif
- WAV: wav
- Monkey's audio: ape
## Playlists and internet radio
forked-daapd supports M3U and PLS playlists. Just drop your playlist somewhere
in your library with an .m3u or .pls extension and it will pick it up.
If the playlist contains an http URL it will be added as an internet radio
station, and the URL will be probed for Shoutcast (ICY) metadata. If the radio
station provides artwork, forked-daapd will download it during playback and send
it to any remotes or AirPlay devices requesting it.
Instead of downloading M3U's from your radio stations, you can also make an
empty M3U file and in it insert links to the M3U's of your radio stations.
Support for iTunes Music Library XML format is available as a compile-time
option. By default, metadata from our parsers is preferred over what's in
the iTunes DB; use itunes_overrides = true if you prefer iTunes' metadata.
forked-daapd has support for smart playlists. How to create a smart playlist is
documented in
[README_SMARTPL.md](https://github.com/ejurgensen/forked-daapd/blob/master/README_SMARTPL.md).
## Artwork
forked-daapd has support for PNG and JPEG artwork which is either:
- embedded in the media files
- placed as separate image files in the library
- made available online by the radio station
For media in your library, forked-daapd will try to locate album and artist
artwork (group artwork) by the following procedure:
- if a file {artwork,cover,Folder}.{png,jpg} is found in one of the directories
containing files that are part of the group, it is used as the artwork. The
first file found is used, ordering is not guaranteed;
- failing that, if [directory name].{png,jpg} is found in one of the
directories containing files that are part of the group, it is used as the
artwork. The first file found is used, ordering is not guaranteed;
- failing that, individual files are examined and the first file found
with an embedded artwork is used. Here again, ordering is not guaranteed.
{artwork,cover,Folder} are the default, you can add other base names in the
configuration file. Here you can also enable/disable support for individual
file artwork (instead of using the same artwork for all tracks in an entire
album).
For playlists in your library, say /foo/bar.m3u, then for any http streams in
the list, forked-daapd will look for /foo/bar.{jpg,png}.
You can use symlinks for the artwork files.
forked-daapd caches artwork in a separate cache file. The default path is
`/var/cache/forked-daapd/cache.db` and can be configured in the configuration
file. The cache.db file can be deleted without losing the library and pairing
informations.
## Library
The library is scanned in bulk mode at startup, but the server will be available
even while this scan is in progress. You can follow the progress of the scan in
the log file. When the scan is complete you will see the log message: "Bulk
library scan completed in X sec".
The very first scan will take longer than subsequent startup scans, since every
file gets analyzed. At the following startups the server looks for changed files
and only analyzis those.
Changes to the library are reflected in real time after the initial scan. The
directories are monitored for changes and rescanned on the fly. Note that if you
have your library on a network mount then real time updating may not work. Read
below about what to do in that case.
If you change any of the directory settings in the library section of the
configuration file a rescan is required before the new setting will take effect.
Currently, this will not be done automatically, so you need to trigger the
rescan as described below.
Symlinks are supported and dereferenced, but it is best to use them for
directories only.
### Pipes (for e.g. multiroom with Shairport-sync)
Some programs, like for instance Shairport-sync, can be configured to output
audio to a named pipe. If this pipe is placed in the library, forked-daapd will
automatically detect that it is there, and when there is audio being written to
it, playback of the audio will be autostarted (and stopped).
Using this feature, forked-daapd can act as an AirPlay multiroom "router": You
can have an AirPlay source (e.g. your iPhone) send audio Shairport-sync, which
forwards it to forked-daapd through the pipe, which then plays it on whatever
speakers you have selected (through Remote).
The format of the audio being written to the pipe must be PCM16.
You can also start playback of pipes manually. You will find them in remotes
listed under "Unknown artist" and "Unknown album". The track title will be the
name of the pipe.
Shairport-sync can write metadata to a pipe, and forked-daapd can read this.
This requires that the metadata pipe has the same filename as the audio pipe
plus a ".metadata" suffix. Say Shairport-sync is configured to write audio to
"/foo/bar/pipe", then the metadata pipe should be "/foo/bar/pipe.metadata".
### Libraries on network mounts
Most network filesharing protocols do not offer notifications when the library
is changed. So that means forked-daapd cannot update its database in real time.
Instead you can schedule a cron job to update the database.
The first step in doing this is to add two entries to the 'directories'
configuration item in forked-daapd.conf:
```
directories = { "/some/local/dir", "/your/network/mount/library" }
```
Now you can make a cron job that runs this command:
```
touch /some/local/dir/trigger.init-rescan
```
When forked-daapd detects a file with filename ending .init-rescan it will
perform a bulk scan similar to the startup scan.
### Troubleshooting library issues
If you place a file with the filename ending .full-rescan in your library,
you can trigger a full rescan of your library. This will clear all music and
playlists from forked-daapd's database and initiate a fresh bulk scan. Pairing
and speaker information will be kept. Only use this for troubleshooting, it is
not necessary during normal operation.
## Command line and web interface
forked-daapd is meant to be used with the clients mentioned above, so it does
not have a command line interface nor does it have a web interface. You can,
however, to some extent control forked-daapd with [MPD clients](#mpd-clients) or
from the command line by issuing DAAP/DACP commands with a program like curl.
Here is an example of how to do that.
Say you have a playlist with a radio station, and you want to make a script that
starts playback of that station:
1. Run 'sqlite3 [your forked-daapd db]'. Use 'select id,title from files' to get
the id of the radio station, and use 'select id,title from playlists' to get
the id of the playlist.
2. Convert the two ids to hex.
3. Put the following lines in the script with the relevant ids inserted (also
observe that you must use a session-id < 100, and that you must login and
logout):
```
curl "http://localhost:3689/login?pairing-guid=0x1&request-session-id=50"
curl "http://localhost:3689/ctrl-int/1/playspec?database-spec='dmap.persistentid:0x1'&container-spec='dmap.persistentid:0x[PLAYLIST-ID]'&container-item-spec='dmap.containeritemid:0x[FILE ID]'&session-id=50"
curl "http://localhost:3689/logout?session-id=50"
```
## Spotify
forked-daapd has support for playback of the tracks in your Spotify library. It
must have been compiled with the `--enable-spotify` option (see
[INSTALL](https://github.com/ejurgensen/forked-daapd/blob/master/INSTALL)).
You must also have libspotify installed, otherwise Spotify integration will not
be available. Unfortunately the library is no longer available from Spotify, and
at the time of writing they have not provided an alternative. You can, however,
still get libspotify here:
- Debian package (libspotify-dev), see https://apt.mopidy.com
You must also have a Spotify premium account. If you normally log into Spotify
with your Facebook account you must first go to Spotify's web site where you can
get the Spotify username and password that matches your account. With
forked-daapd you cannot login into Spotify with your Facebook username/password.
The procedure for logging in to Spotify is a two-step procedure due to the
current state of libspotify:
1. Put a file in your forked-daapd library containing two lines, the first being
your Spotify user name, and the second your password. The filename must have
the ending ".spotify"
2. Delete the file again - forked-daapd will have read it.
3. forked-daapd will log in and add all music in your Spotify playlists to its
database. Wait until completed (follow progress in the log file).
4. In a browser, go to http://forked-daapd.local:3689/oauth and click the link
to authorize forked-daapd with Spotify.
Spotify will automatically notify forked-daapd about playlist updates, so you
should not need to restart forked-daapd to syncronize with Spotify. However,
Spotify only notifies about playlist updates, not new saved tracks/albums, so
you need to repeat step 4 above to load those.
Forked-daapd will not store your password, but will still be able to log you in
automatically afterwards, because libspotify saves a login token. You can
configure the location of your Spotify user data in the configuration file.
To permanently logout and remove credentials, delete the contents of
`/var/cache/forked-daapd/libspotify` (while forked-daapd is stopped).
Limitations:
You will not be able to do any playlist management through forked-daapd - use
a Spotify client for that. You also can only listen to your music by letting
forked-daapd do the playback - so that means you can't stream from forked-daapd
to iTunes.
## LastFM
If forked-daapd was built with LastFM scrobbling enabled (see the
[INSTALL](https://github.com/ejurgensen/forked-daapd/blob/master/INSTALL) file)
you can have it scrobble the music you listen to. To set up scrobbling you must
create a text file with the file name ending ".lastfm". The file must have two
lines: The first is your LastFM user name, and the second is your password. Move
the file to your forked-daapd library. Forked-daapd will then log in and get a
permanent session key.
You should delete the .lastfm file immediately after completing the first login.
For safety, forked-daapd will not store your LastFM username/password, only the
session key. The session key does not expire.
To stop scrobbling from forked-daapd, add an empty ".lastfm" file to your
library.
## MPD clients
If forked-daapd was built with support for the [Music Player Deamon](http://musicpd.org/)
protocol (see the [INSTALL](https://github.com/ejurgensen/forked-daapd/blob/master/INSTALL)
file) you can - to some extent - use clients for MPD to control forked-daapd.
By default forked-daapd listens on port 6600 for MPD clients. You can change
this in the configuration file.
Currently only a subset of the commands offered by MPD (see [MPD protocol documentation](http://www.musicpd.org/doc/protocol/))
are supported by forked-daapd.
Due to some differences between forked-daapd and MPD not all commands will act
the same way they would running MPD:
- consume, crossfade, mixrampdb, mixrampdelay and replaygain will have no effect
- single, repeat: unlike MPD forked-daapd does not support setting single and repeat separately
on/off, instead repeat off, repeat all and repeat single are supported. Thus setting single on
will result in repeat single, repeat on results in repeat all.
Following table shows what is working for a selection of MPD clients:
| Client | Type | Status |
| --------------------------------------------- | ------ | --------------- |
| [mpc](http://www.musicpd.org/clients/mpc/) | CLI | Working commands: mpc, add, crop, current, del (ranges are not yet supported), play, next, prev (behaves like cdprev), pause, toggle, cdprev, seek, clear, outputs, enable, disable, playlist, ls, load, volume, repeat, random, single, search, find, list, update (initiates an init-rescan, the path argument is not supported) |
| [ympd](http://www.ympd.org/) | Web | Everything except "add stream" should work |
